A better other option might be to just use a separate hg repo for download files. This might be easier to sync with the website too... since the website would just pull from the hg repo to sync. Rather than me having to finish a download and sync script for the download page.

Do we still want to resurrect the SAAPBP? We now have builds going on on Travis, Launchpad and Appveyor. Unless there's some special testing we can do by setting up a custom build system, I think it's probably not worth the maintenance.

Now that travisci has macosx builds I don't think it's needed. If someone wants to put in the effort for other platforms, then we can reconsider.
Additionally, the build badges in the readme.rst show the build status. So it's easy for people to see if they broke something.
